Went out last week and heard and felt a bump which it seemed was coming from the lower unit. Happens at higher speed (not at slow speed). Began to feel and hear it more and more. Figured it was the shift cable out of adjustment as I had removed it when doing carb work. Started to happen more and I worried about getting in (I was 40 miles out). So out on the water I adjusted the shift cable(a 7/16 wrench and a phillips was all I needed) kinda hanging off the transom. It was either that or go in at less than 10 miles an hour( a 4 to 5 hour ride in).
After the adjustment motor was good to go. I was able to ride in at full speed, no more issue with the lower unit . I figured the problem was solved. I checked the lower unit lube on Thursday to see if there were any metal bits or shavings on the drain plugs or in the fluid, there was none, the fluid looked good as I had changed it with the impeller a couple of months ago. Yesterday I went out again and all went well , the motor ran fine, no issues for the first 25 miles then the same thing started to happen. Kinda feels like it wants to jump out of gear but then it does not. I attempted the same repair as the last trip out, this time trying to insure it would go into forward as far as possible with the adjustment.. This time the results were not good. The bang or bump would act as I increased throttle . My over the transom cable adjustment did not cure the problem. Of course shifting at the binnacle was a bit out of whack due to my extreme forward adjustment. I was able to make it in just had to take it slow. There was a 4 foot wind chop which was miserable so I could not throttle up anyway but if I tried the bump would be there.
Is this a symptom of l/u about to go out completely ? The cable is only a year or two old, might it have stretched or just be bad, lu is the original.
